Title: System and method for cutting patterns pieces from sheet material
IPC: B26D5/00
Filed: 1973-11-29
Abstract: 1450445 Automatic control of textile machines GERBER GARMENT TECHNOLOGY Inc 29 Nov 1973 [11 Dec 1972] 55378/73 Heading G3N In the processing of cutting information for the cutting of pattern pieces A-F (woven or non- woven fabric), in which the patterns are placed on a marker 46 closely nested, the resulting pattern being digitized and processed to provide control data, for a controller and cutting table, or for recording on tape 26, individual pieces having been digitized by passing along their contours in a given sense, data processor 50 is programmed so that some segments of the pattern pieces are cut in a direction opposite to that in which they were digitized. The data points of such segments, identified during digitizing by an operative, are processed to reverse their sequence, added to the programme of data points for the non-reversed segments, whence the original request as digitized of the reversed segments is deleted from the programme. The resulting programme is processed by known curve and servo algorithms, the resulting cutting programme being stored on tape 26, see Fig. 6 (not shown). Where, on the marker 46, a pair of pieces are tangential, Fig. 3 (not shown), the programme ensures that, piece (A) having been cut, piece (B) is cut towards point (60) only. The programme may include provision for slowdown in the feedrate as point (60) is approached (88), Fig. 6 and Fig. 7 (not shown) at a pre-programmed rate, and/or facility to yaw (20, Fig. 3) the reciprocating cutting blade direction, normally kept tangent to the contour, away from the adjacent, already cut piece (89, Fig. 6), Fig. 8 (not shown). Where a pair of pieces (D, E) Fig. 5 (not shown), share a contour (78-79), processor 50 ensures that, as programmed, the overall contour of both parts is cut first, followed by the line (78-79). The programme includes cutting blade retraction data, distinct feedrates for paths to be followed with blade up being programmed, with slowdown to blade entry locations. The block is lifted, rotated, and plunged for sharp corners. Drilling and marking commands are also programmed. Marker digitization. Optimum disposition of the pieces A-F on marker 46 may be evolved manually, or, using digitizer 42, individual pieces A-F may be digitized together with locating points "+" a generator 44 optimizing the relative positions to minimize waste, or the digitized pieces may be displayed on an oscilloscope, index instrument interacting with the display enabling the parts to be moved about to form the marker pattern to be digitized. Multiple layers of fabric (L), Fig. 1 (not shown) are held on table (12) by a vacuum system, air impervious overlay (16) being provided.' The pieces are for garments or upholstery.

Title: Cereal product
IPC: B02C9/04
Filed: 1969-11-25
Abstract: 1,243,880. Cereal products. RALSTON PURINA CO. 25 Nov., 1969 [25 Nov., 1968], No. 57659/69. Heading A2Q. A cook-in-the-bowl type cereal product is produced in the form of flakes which are from 0.007 to 0.008 inch thickness. Flakes of this critical range of thickness are said to be necessary, particularly when prepared from hard red winter wheat, to ensure the desired quick-cooking properties while at the same time ensuring that the flakes are not so thin that they break up into powder. In order to produce such flakes, hard red winter wheat having a moisture content of about 10 per cent by weight is first broken down on a roll mill and screened to yield a milled fraction with about 80 per cent by weight of the particles having a size greater than No. 42 Tyler mesh. Vitamins and other food supplements, e.g. 5 per cent by weight of wheat germ, may be added to the grain at this stage. The screened fraction is then conducted to an atmospheric screw tempering chamber where steam and water are injected to increase the moisture content to 12-16 per cent by weight, this being carefully controlled, together with careful control of the temperature to between 185 and 220‹F., preferably between 190 and 210‹F., prior to rolling by Lanhoff rolls set to produce flakes of the thickness specified above. The flakes are then collected and dried to a moisture content of 8-9 per cent by weight, flour and fine particles of grain flakes being entrained in the drying air during drying and trapped in a dust collector. The product is then screened to give about 80 per cent by weight of flakes having a particle size greater than No. 42 Tyler mesh. The screened product may be combined with a number of flavouring agents if desired, e.g. 75 per cent of the wheat flakes may be mixed with 18 per cent dextrose, 4 per cent apple flavour and 3 per cent preservatives, salt and spices, or 79 per cent of the wheat flakes may be mixed with 19 per cent brown sugar and 2 per cent flavouring, salt and preservatives.

Title: Holographic blind-landing system
IPC: G01C21/00
Filed: 1971-12-16
Abstract: 1312389 Blind landing aid VEREINIGTE FLUGTECHNISCHE WERKE - FOKKER GmbH 16 Dec 1971 [16 Dec 1970] 58540/71 Heading H4D In a blind landing system an animate simulated view of the landing site is presented to the pilot by means of reading out a halogram of the site and varying the halogram under the control of laser position finding equipment. The position finding equipment co-operates with reflectors 40, Fig. 2, sited along the run-way. The pulsed beam from laser 12, Fig. 1, is widened and scanned across the landing site by respective optics 14 and 15. A portion of the transmitted beam is directed to photo-diode 19 by microns 17 and 18. A zoom lens 22 receives the light reflected from reflectors 40 and particularly that from enlarged, touch-down point reflector 40 and directs it, via an image amplifier 23 to a TV camera 24. A portion of the reflected light is directed to photomultiplier 26 by mirrors 21, 25. The outputs of the TV camera 24, the photo-diode 19, the photomultiplier 26 and the laser pulser 13 are fed to a computer 27 which gives control signals for the scanner 15 and zoom lens 22 and also for the direction control of the whole laser positionfinding equipment 10 on to the landing site. The computer also provides adjusting signals for the halogram store 31 such that the view of the landing site on drop-down screen 32 is controlled according to the detected position of the aircraft. The computer 27 also controls the zoom lens 33 directing the beam from laser 34 on to the halogram.

Title: Steering mechanism for tracked vehicles
IPC: B62D11/14
Filed: 1972-12-19
Abstract: 1359375 Steering for tracked vehicles MARSHALL-FOWLER Ltd 19 Dec 1972 [20 Dec 1971] 58970/71 Heading B7H In a steering system for a tracked vehicle of the kind described in Specification 1,259,281 a brake is associated with a reaction member in the form of a disc 16 of each planetary gear system, each brake being applied by spring force which may be opposed when required by hydraulic means controllable directly by the vehicle driver. In a preferred embodiment, Fig. 1, disc 16 is normally held between peripheral friction pads only a pair 17, 19 being shown in a caliper 18, the pad 19 being secured to a piston 20 which is mounted in a cylinder in the caliper 18. The disc 16 is normally held between pads 17, 19 by a force generated by disc springs 101 which force may be opposed by an hydraulic force generated in an annular volume 21. In one type of hydraulic system employed, Fig. 2, a selector valve 104 which is controlled by a lever or foot pedal serves to connect either a supply line 106 or a return line 108 to the operating line 107 which may act via a pressure intensifier 109 to generate the desired hydraulic pressure in pipe 29 for the pistons 20. The valve 105 in the position shown in Fig. 2 permits a small flow of fluid throughout the system when the volume 21 is not pressurized. In another hydraulic system, Fig. 3, only flushing of the low pressure side of intensifier 109 occurs, the valve 118 allowing fluid flow only in the direction of arrow A. A reservoir 119 ensures volumes 21 are always full. The hydraulic system of Fig. 4 (not shown) has no facility for fluid flushing but may be modified as in Fig. 5, in which the check valve 120 is opened each time the low pressure side of the intensifier is unpressurized thus ensuring that volume 21 is always pressurized by a spring biased plunger 123 in reservoir 119. To prevent unintentional application of the brakes due to a rise in temperature on the high pressure side of the intensifier a check valve, Fig. 7 (not shown), is used in which leakage in the normal blocked direction is allowed at a low volume rate.
